Preheat your oven to 200c and place the tortillas in a single layer on a large baking tray, drizzle with one tablespoon of oil. Cook for 8 minutes until crisp. If they start to puff up of curl up too much, place another baking tray on top to keep them flat.

Heat one tablespoon of oil in a frying pan, add the onion and cook for 5 minutes until softened. Add the spices, oregano, vinegar and honey then cook for a few more minutes, stirring constantly. Add the beans and seasoning, and cook for about 5 more minutes.

Once the beans are hot, mash them gently with a potato masher. Add a splash of water and cook for a minute or so longer and let the water be absorbed.
